TN-100 Total nitrogen analyzer
for liquid and gaseous samples
The TN-100 is provided with all the accessories required for measurement of non-aqueous and aqueous samples The use of the model ASC-150L liquid auto sampler allows completely automated measurement of up to 50 samples.A reduced pressure system is used that is essential for non-aqueous samples.
Five types of measuring ranges make it possible to accommodate a wide range of sample types from low concentrations to high concentrations. Safe design featuring continuous monitoring of supplied gas flow rate, reaction tube temperature and other parameters along with activation of an interlock function during system abnormalities.
